Mainland and Hong Kong stocks dropped by the most in nearly a month on Friday as an overnight tumble on Wall Street soured sentiment.

The benchmark Hang Seng Index ended trading for Friday down 500 points, or 1.85 percent, at 26,572, with the biggest losers including media, internet and consumer counters.

The benchmark Shanghai Composite Index closed down 0.97 percent at 3,990 while the Shenzhen Component Index was 1.93 percent lower at 13,216 and the ChiNext Index, tracking China's Nasdaq-style board of growth enterprises, lost 2.82 percent to close at 3,111. China's blue-chip CSI300 Index also closed down 1.6 percent.

The Hong Kong and Shanghai benchmark losses were the worst since October 17.

The combined turnover at the Shanghai Composite and Shenzhen Component indexes was nearly 1.96 trillion yuan, down from 2.04 trillion yuan on Thursday.

Shares related to water and gas utilities, furniture and paper products led the gains, while those related to ceramics and textile machinery suffered major losses. (Reuters/Xinhua)
